INKING-ROLL TRUCK.

Application filed January 9, 1918.

To aZZ whom t may concern.'

Be it known that We, FREEMAN J. BRAD- LEY and MERRILL C. DIONNE, citizens of the United States, and residents of Fostoria, in the county of Seneca and State of Ohio, have made certain new and useful Improvements in Inking-Roll Trucks, of which the following is a specification.

Our invention relates to improvements in inlring roll trucks, being more particularly in the nature of an expansible roller arranged to be fitted on each of the trunnions of an inking roll, and it consists in the con structions, combinations and arrangements herein described and claimed.

An object of our invention is to provide an inking roll truck including a relatively xed expansion rim With a relatively movf able expansion cone, a plurality of expanding segments located between these members, bein adapted to increase the diameter o f ya tire ocated between the cone and the rim.

@ther objects and advantages Will appear in the following specification, reference being had to the accompanying drawing in which,

Figure 1 is a side elevation showing the improved truck applied to one of the Ltrunnions of an inlriner roll.

Fig. 2 is a longitudinal section of the truck.

Fig. 3 is an elevation showing the expansion Irings and segments in place on the expanslon rim.

Fig. 4 is an elevation :of the expansion cone.

Fig. 5 is a detail perspective View of one rof the "expansion segments, and

Fig.` 6 isa detail view of a wrench employed in adjusting the expansion cone. y

In carrying out our invention, We provide an expansion cone 1,Which has a bore 2 Ydisposed coaxially thereof. The cone 1- includes an annular shoulder 3. The body portion of the member 1 is in the shape of a irustum of a gone and .provides the conical surface 4jfrom'ivhic`h the member 1 obtains its name.

The expansion cone l is further reduced beyond the summit of the frustuprir 4 and forms an annular shoulder 5. The expan sion cone 1 is still further reduced beyond the annular shoulder 5, and this reduced ortion is threaded as at 6, to receive the lock and jam nuts 7 and 8 respectively.

the segments may be increased or decreased as experience may dictate. y

The expansion segments are Wedge-shaped and the bases of the segments are substantially on the same plane with the summit of the frustum 4. An expansion rim 10 forms an abutment for the bases of the expansion segments When the expansion cone 1 is forced toward the expansion rim and the segments 9 are displaced radially bv virtue of tbe Wedging action of the expansion cone on the segments.

Formed in the face of the expansion rim 10 opposing the expansion seoments. is a conical recess 11. which is so disposed that it may receive the adiacent end of the frusturn 4 when the cone and the rim are drawn tofrether. Tbeconica-l recess ll hes a counter-bore `1,2 which is adapted to receive the annular shoulder 5 of.` the expansion cone. A pluralitv of expansion rings 13 encircle the expansion segments. suhstantiallv as indica'ted in the drawing.' These rings consist of split springs. Thev are made of spring metal suitable for the purpose. Thov form au exnansible tive on the inking roll trunk. The location ot' the split portions of Hw Pings is sfagaered es shown in Fim l. @o Haat these snlit portions rnav 'ont come Momtber nv :line im transversnlv of the tire. The mbsf -sibilifv of evcessive wea-r and also the* ci the chartenimfr of the rimvs is *hns nbvintod 'The normal diarreter of the expansion rings 13 is'slifhtlv in excess of that of the annular shoulder 3 of the cone 1. and lasimilar shoulder 14 of the rim 10. A Wrench 15 illustrated in Fig. 6. is emoloved in adiistinfr'` the nuts 7 and 8 on the threaded end 6.

- The Operation of the device is as follows:

The invention; is inthe nature. of a rollerv havin-e an-exnansible rim ard this .roller is landtinarilv. ealleduthemprinting roll truck in the nomenclature of the printing trade. The truck is ttedon the-trunnions: LG on 17. The truck runs on a track 18 during` the movement of the inking roll over the type.

This leads to a consideration of the purpose of the expansible rim or tire of the ot the device is that of a ,said rim having 1 sion cone movable toward the rim and truck. Ordinarily the tire of the truck and the inking roll are of the same diameter. Varying weather conditions cause the inking roll to swell to a greater or lesser dcree. Should the swollen inking roll now Ee run over a torni having more or less vertical rulings for printing the lines on the paper, the surface of the swollen roll may be cut and seriously damaged. t

It is novi7 that the truck tire or run is adjusted to compensate for the swollen inkin roll. The Wrench is taken and applied to the lock and jam nuts 7 and 8 The nut 7 is turned' to draw the expansion cone 1 toward the expansion rim l() wherein the expansion segments 9 are displaced radially and the tire of the truck consist` ing of the expansion rings 13, is expanded to the same diameter' of the swollen inking roll. To eifeet this adjustment, it is not necessary for Vthe printer to leave the feed ing position at the press. A very fine adjustment can be made With this device: n variation of a thousandth of an inch being easily obtained.

As the expansion cone 1 is forced toward the rim 10, the summit of the frustuni #l moves into the conical recess 11, and the expansion segments 9 are forced radially outward by reason of the abutment of .the

bases of the segments on the expansion rim,

and the action of the cone 4 on the wedge- 'shaped surfaces of the segments.

" While the construction and arrangement generally7 preferred form, obviously modications and changes may be made Without departing from the spirit of the invention or the scope of the claims.

7e claim:

1. In an inking r ll truck, an expansion cone having an annular shoulder, arcuate triangular Wedges superposed on the expansion'leone With the ases adjacent to said shoulder, and an expansion rim engaging y theV bases o thewedge's, and having a conical recess with a counter bore, to receiveY the end of the| cone and the annular shoulder frespectively, and rovide a stop for limiting the adjustment cone.

l 2. Inan inking ofthe rim toward the roll truck, Van expansion iriin' having va 'surface perpendicular to the airis of the inkng roll to form an abutment,

a conical recess, ,an expan- "partly entering said recess, means for drawedpies-'ofmnispatem may'be obtained for five centseacli. by addressing the Washington, I),l C, l

ing the cone toward the rim, a plurality of wedge-shaped segments bearing on the conical surface of the cone and engaging the abutment of the expansion rim, and a tire including a plurality of split rings, encircling said seginents.

3. In an inking roll truck, an expansion riin having a conical recess and a counterbore,an expansion cone including the frustoconical body having a reduction at the sunk mit forming an annular shoulder movable into the counter-bore, and a threaded portion projecting beyond the rim said expansion cone having a co-axial bore, a plurality of Wedge-shaped expansion segments engaging the truste-conical body and contacting the expansion riin at the bases,l a tire including a plurality of split ringsI having the split portions staggeredly arranged, encircling said segments, and lock and jam nuts on the threaded portion adapted to draw the cone toward the rim to expand Ihe rings.

4. In an inking roll truck, an expansion rini having a surface perpendicular to the axis of the inking roll to forni an abutment, said surface having a conical recess and a counter-bore, the periphery of the expansion rim being rabbeted at one edge to provide an annular shoulder, an expansion cone consisting of a truste-conical body having a reduction at the summit of the cone to leave an annular shoulder movable in the counterbore, and a threaded portion projecting be yond said shoulder and through said counter-bore, the end of the expansion cone being receivable in the conical recess when the parts are screwed together, the peripheral ed e of the expansion cone having a rabbetec portion to provide an annular shoulder, a plurality of wedge-shaped expansion segments engaging the expansion rim abutment at the bases, the eX osed ortions of said segments normally lying ush with the peripheral portions of said rim and said cone beneath said annular shoulders, a tire including a plurality of split rings encirclin said segments and disposedin the space etween said annular shoulders, 4said shoulders preventing the rings from sipping off, and lock and jam nuts on the threaded portion of said expansion cone to draw the cone toward the rim to expand the rings;
